Move axis hiding into `.overlay_plotitem()`

Since we pretty much always want the 'bottom' and any side that is not
declared by the caller move the axis hides into this method. Lets us
drop the same calls in `.ui._fsp` and `._display`.

This also disables the auto-ranging back-linking for now since it
doesn't seem to be working quite yet?
